The safe filling of gas cylinders requires that the persons performing the operation have detailed and expert knowledge of, in particular gas properties, cylinder design, plant operation and relevant legislation. This is in addition to use of the appropriate equipment and inspection of the cylinder to be filled.
Experience has shown that transfilling of gases, usually from a larger cylinder to a smaller cylinder, by unqualified persons have caused serious incidents including a number of fatalities. EIGA's position is that only competent and trained professionals transfill industrial, medical and food grade gases using cylinders and equipment specifically designed for the cylinder transfilling operation. Transfilling of medical gases is only allowed if a specific manufacturing licence has been issued by the competent health authority.
